Generate Type Members

Code | Generate...Alt+Insert

With JetBrains Rider, you can quickly generate different type members. To view the list of available code generation options for the current type, press Alt+Insert or choose Code | Generate... in the main menu.

Depending on your settings, stubs for new members can be generated in different ways. For example, they can throw new NotImplementedException(), return default value, or include code that will not compile. You can configure these and other preferences on the Editor | Members Generation page of JetBrains Rider settings Ctrl+Alt+S.
